In a relatively simple setup consisting of a microchip laser as pump source and
two hydrogen-filled hollow-core photonic crystal fibers, a broad, phase-locked,
purely rotational frequency comb is generated. This is achieved by producing a
clean first Stokes seed pulse in a narrowband guiding photonic bandgap fiber via
stimulated Raman scattering and then driving the same Raman transition
